Abstract

A dual‐mode bandpass filter (BPF) using microstrip patch resonator is proposed. Open‐stubs are added on the feed‐lines to suppress the spurious response and improve the stopband rejection effectively with little increase in circuit size. Furthermore, a reduced‐size dual‐mode BPF with spurious response suppression using microstrip slotted‐patch resonator is successfully designed. The simulated and measured results are presented and both are in good agreement. © 2007 Wiley Periodicals, Inc.

A novel microstrip transversal bandpass filter is proposed by replacing the full-wavelength resonator with two shorter resonators; in order to achieve simultaneous spurious response suppression and dual zero implementation. These two zeros can be easily tuned by the above resonators. A prototype fil
